Title: Device and process for dimensionally stable sintering of ceramic pre-shaped articles

Brief Patent Description - Full Patent Description - Patent Claims

The Patent Description & Claims data below is from USPTO Patent Application 20080286718, Device and process for dimensionally stable sintering of ceramic pre-shaped articles.

1. A device for dimensionally stable sintering of ceramic pre-shaped dental articles, comprising a suspension system having: a) a base structure with at least one suspension point at a height suitable for suspending an article to be sintered; and b) a suspension element moveably connected to said suspension point for supporting said article to be sintered, wherein said suspension element itself forms a swing on which said article to be sintered is arrangeable.

2. The device of claim 1, wherein said base structure comprises two suspension points and the suspension element is connected to both of them.

3. The device of claim 1, wherein said base structure comprises rods that are mountable to a support.

4. The device of claim 3, wherein said support is a honey-comb structure.

5. The device of claim 4, wherein the base structure comprises two spaced apart rods.

6. The device of claim 5, wherein each of said rods is adapted to moveably hold opposing end portions of the suspension element.

7. The device of claim 6, wherein each of said rods comprises an eyelet at its upper end portion to which said suspension element is moveably linked.

8. The device of claim 1, wherein said suspension element is an integral swing.

9. The device of claim 1, wherein said suspension element is formed of a plurality of moveably linked sections.

10. The device of claim 9, wherein said moveably linked sections of said suspension element are linked by eyelets.

11. The device of claim 1, wherein the suspension system is made of a material which is inert vis-à-vis the sintering process and does not result in adhesion to the article and does not contaminate the latter.

12. The device of claim 1, wherein the suspension element is made of wire material.

13. A process for dimensionally stable sintering of ceramic pre-shaped dental articles, comprising the steps of: a) providing a suspension system with base structure with at least one suspension point at a height suitable for suspending an article to be sintered, and a suspension element moveably connected to said suspension point for supporting said article to be sintered, wherein said suspension element itself forms a swing; and b) placing said article to be sintered onto said swing.

14. The process of claim 13, wherein said suspension system is mounted on a support, preferably a honey-comb structure.

15. The process of claim 14, wherein said dental article is a prosthesis.
